Beschreibung
Zusammenfassung:	A wireless power transmitter may include a transmit coil configured to generate a wireless power signal for wireless power transfer, at least one secondary sensing coil configured to generate a signal responsive to a magnetic flux field generated during the wireless power transfer, and control logic configured to detect at least one condition of a wireless power transfer system responsive to detecting distortion in the magnetic flux field from the at least one signal received from the secondary sensing coil. A related method may include generating with a wireless power transmitter a wireless power signal, generating with a plurality of secondary sensing coils one or more signals responsive to a magnetic flux field generated during the wireless power transfer, and detecting at least one condition of a wireless power transfer system responsive to the one or more signals generated by the plurality of secondary sensing coils.
